These downwardly extending side arm por-- tions are preferably positioned so that their lower ends will terminate just above the medial line l8 through the lenses and by-this constructionthe bendable arm 19 of the noseguard 20 may be attached on this medial line, which is of importance to mountings of this construction. Also this arm 19 of these nose-guard members is formed bendable so that the nose-guard may be adjusted independently of the bridge member to fit and properly engage the noses of different wearers which vary to a considerableextent.

By this adjustment, the number of different sizes of mountings to be carried in stock may be greatly reduced, thus materially reducing the investment in stock of the dealer, which is of considerable importance, particularly where the mountings are of precious metals and also by this independent adjustment of thebridge member and the nose guards, accurate fitting of the mounting to the faces of the different wearers is permitted. V

While I have described certain construction forms which embody the principles of my invention, it is obvious that other desired changes in arrangement may be'made within the spirit and the scope of the invention as defined in the (appended claims.

said bridge being provided with a cross bar having a rearwardly extending arm folded upon itself at each end thereof, both folds of said arms being disposed in substantially the same hor izontal plane and in the same plane as said cross bar, the end portions of said arms extending downwardly a substantialdistance along the eyewires providing an extended attaching surface.

2. An ophthalmic mounting having spaced eyewires, a high bridge connecting said eyewires formed of a length of 'wire folded to'provide a cross bar portion having at each end thereof and in the horizontal plane therewith a rearwardly extending bendable arm folded uponitself to provide two parallel parts with its two parts connected by a return bend, the end portions of each arm extending downwardly a substantial distance to a point adjacent the medial line through the eyewires, said downwardly extending portion providing an extended surface for attachment to the eyewires.

3. An ophthalmic mounting having spaced eyewires, a horizontal bridge member connecting said eyewires, said bridge member being provided with end portions extending rearwardly and in the same horizontal plane" therewith, each being then folded upon itself forming bendable double substantially parallel side arms, the free end portionsof the return arm portion extending downwardly substantially at right angles to the plane of said arms substantially to the medial line through the lenses, and a pair of nose guards supported on the mounting adjacent the attaching ends of the bridge.

4. An ophthalmic. mounting having spaced eyewires,- a bridge connecting said eyewires being formed of "alength of bendable wire folded to form a cross bar having rearwardly extending arm portions each folded upon itself to provide forwardly extending portions, both parts of the arm being disposed in substantially the same horizontal plane as that of the cross bar the end portions of said arms extending downwardly along said eyewires a substantial distance providing an extended surface for attachment;

5. An ophthalmic mounting having spaced eyewires, a bendable bridge connecting said eyewires, said bridge comprising a cross bar with its end portions extending rearwardly in substantially the same horizontal plane as that of the cross bar, and then doubled and extending forwardly to provide double side arms connected by a return bend the end portions of said arms extending downwardly along said eyewire a substantial distance and a pair of nose guards attached to said eyewires at the lower ends of said EARLE J.
